TRAVELING LAWN-SPRINKLER.

Specification of Letters Iaten't.

Application'med April 20, 1916. Serial No. 92,473.

To all whom it may concern: Be it known. that we, WILLIAM C. Tom) andJAMES W. PoMnRoY, citizens of the D- minion of Canada, residing atVictoria, in the Province of British Columbia,'Canada, have inventedcertain new and useful improvements in Traveling Lawn-Sprinklers, ofwhich the following is a specification.

This invention relates to a rotatable sprinkler of that class whereinthe water is delivered in a free end of a pipe which travels in acircular path about a central standard to which a ed by a small impactwater service is connected.

The device is an improvement on that on which Patent No. 1,108,528 wasgranted to us on the 25th August, 1914, and the improvement is directedto the use of a rotatable inclined spraying nozzle instead of arotatable reaction sprinkler such as is set forth in the aforeme'nt'gmedpatent, rotation of the inclined nozzle ibout it's axisand rotation ofthe wheel which supports the free end of the radial pipe and carries itin a circle around the central standard, being efiectturbine throughwhich the water passes to the spraying nozzle.

It is found that the nozzle will deliver the spray of water to a greaterdistance than it can be thrown by the use of a rotatable "sprinkler andthis rotatable spraying nozzle mounted. on the end of the radial pipegives a considerably increased radius of action.

eral incidental features to which attention is drawn in the followingspecification, reference being made to the drawings by which itigsaccompanied, in which:

1 kler complete showing the as mounted on the free end of the centralstandard about which it circles.

Fig. 2 is a part section through the axis of the water delivery to theturbine and therefrom to the spraying nozzle.

Fig. 3 is a plan of the same, and Fig. 4, a side elevation looking inthe direction of the arrows 4. V

In these drawings 2 represents the tubular central standard which isconnected at 3 to a water service which may either be a permanentconnection to an underground water distribution pipe or may be made bymeans of an ordinary garden hose pipe. About on the pipe itself betweencollars. 'plpe 4 is finely divided state from thea pinion 14, the teethof teeth formed in the edge of the rim of the gure 1 1s a side elevationof the sp'rinspraying device this central standard 2 the horizontallydisposed pipe 4 of any convenient length is radially movable, and thefree end of it is supported on a wheel 5 preferably mounted If the ofany considerable length the same :may be trussed to impart the requiredrlgldlty, or it may have an intermediate sup.- port wheel 6 to sustainits weight.

The free end of the radial pipe 4 is upturned as at 7 outside thesupportwheel 5, and secured on the .upper end of the upturned portion 7is a light metal casing 8 within which is rotatably mounted a turbinewheel 9. The shaft 10 of this turbine has a worm 11 secured on itoutside the easing, which worm meshes in the teeth of a worm wheel 12secured on a shaft 13 rotatable in a bearing secured or integral withthe casing 8. v f On the lower end of the shaft 13 is secured which meshwith support wheel 5.

I The direction of the upturned portion 7 of the radial pipe isapproximately tangential to the periphery of the turbine and the waterdelivers to the vanes or buekets'of the turbine through a, conicaldelivery jet 15.

.The water delivery from the turbine 1s parallel to the axis of the jet15 and in a bushmg 21 secured in it is rotatably mounted a delivery pipe16 which is gland-packed or The present invention also comprises sevhasother provision to avoid leakage.

On this rotatable pipe 16 a small gear wheel 17 is secured,- the gearwheel having a diametrically elongated aperture 18 in which it isadjustably secured on the pipe 16 between nuts threaded thereon, so thatany desired measure of eccentricity within the scope ofv the elongation18 may be imparted to the periphery of the gear. The teeth of this gearwheel 17 mesh with those of a corresponding wheel 19 secured in asimilar manner upon the upper end of the worm-wheel shaft 13.

On the upper end of the delivery pipe 16 is secured by a ball and socketconnection a bent nozzle pipe 20, so that the angle of deliver the waterfrom the nozzle may be -varie to suit the requirementsof the pres-Patented Feb. h, limit.

pipe 4, 7 and through the turbine 9, not only directly rotates thenozzle 20 about the axis on which it is mounted but through the worm, 11and worm wheel 12 slowly drives the support wheel 5 and thereby carriesthe rotating sprinkler around a circular path about the standard 2.

If rotation of the Water distributing nozzle 20 is uniformit willobviously bestow the same amount of water within the circle of its path,as it does outside the same, although the area to be sprinkled outside.is much greater than that Within. It is to correct this that the gears17, 19 are eccentrically mounted on their axes, so that the rotationalvelocity of the nozzle is reduced during the outer part of its movementand increased during the inner part.

aving now particularly described our invention, we hereby declare thatwhat w e claim as new and desire to be protected in by Letters Patent,is:
